  What is progressive scan? - A Word Definition From the Webopedia Computer Dictionary
Progressive scan (also known as known as 480p) is one of two methods used for "painting" an image on a television screen (the other being interlaced scan), where the lines are drawn in one at a time in sequential order.
Progressive scanning results in a more detailed image on the screen and is also less susceptible to the flicker commonly associated with interlaced scanning.
Progressive scan is now the standard of choice for both DVD video and DTV.

  Line Doublers and De-Interlacers
Interlaced scanning, painting 480 scan lines on the screen as two 240 line fields every 30/th of a second (for NTSC), was invented to get the best combination of horizontal resolution, vertical resolution, and freedom from flicker using the limited bandwidth of the TV broadcast channel.
Because progressive scan has eliminated the flicker and fade of the odd scan lines as the even lines are drawn, feathered side edges as the subject moves are more noticeable.
When progressive scan video is constructed using the weave method exclusively, viewers may see the feathered side edges of moving subjects, as the even scan lines show the subject in a dfferent position from the odd scan lines.

 What is Progressive scan 3/2 pulldown explained scanning help
Because we are scanning at twice the speed, we can draw an entire frame in the same amount of time it takes an interlaced system to draw a single field.
But with progressive, each "field" is now a complete picture including all scan lines, top to bottom, so we will now call it a frame, and we are showing 60 of those per second.
The term commonly used to restore the progressive image is deinterlacing, though we think it is more correct to call it re-interleaving, which is a subset of deinterlacing.

 Panasonic Progressive Scan Explained
Interlaced scanning combines two fields to generate a picture of 525 scan lines (480 of which are displayed).
Your television projects an interlaced image by first scanning the 240 odd-numbered lines of one field (in 1/60th of a second), followed by the 240 even-numbered lines of the other field (in 1/60th of a second).
Our progressive scan DVD players have a progressive video processor, which enables all 525 lines (480 of which are displayed) to be scanned at the exact same time; two interlaced fields are combined into one progressive frame.

 Guide to Progressive-Scan Technology   (Site not responding. Last check: )
This is called scanning, and each of the lines drawn by the electron beam is known as a scan line.
Furthermore, the characteristic "flicker" associated with interlaced scanning (particularly problematic when the image contains fine horizontal details that are present in only one of the two interlaced fields) is noticeably reduced with progressive scanning, making it easier on your eyes.
When an image moves quickly across the screen, the difference in its position from one field to the next becomes apparent, and the interlacing visually combines disparate fields, creating an effect known as "feathering" or "combing." Image definition becomes blurry and indistinct when movement occurs, but clarity is restored once the image becomes stationary again.

 Progressive-scan video - CNET reviews
To illustrate the meaning of progressive scan, let's take a look at that old analog TV in your living room.
Since the entire image is drawn at one time--as opposed to an interlaced image where the even lines are drawn first, followed by the odd lines--a progressively scanned video image looks more stable than an interlaced one.
Progressive scan also introduces fewer motion artifacts, such as jagged diagonal lines and movement in fine detail, into the picture.

The odd lines are scanned (drawn on the screen) in 1/60th of a second, and the even lines follow in the next 1/60th of a second.
Interlaced scan splits the image into two fields, alternating between the even (2,4,6…) and odd (1,3,5…) scan lines every 1/60th second, and effectively displaying a full frame every 1/30th second.
Progressive scan, on the other hand, displays all the lines at once (1,2,3,4…), displaying a full frame every 1/60th second.
